“The Terrascope” -Whole Earth Telescope


gravitational lensing


Unless there’s a planet more advanced existing in the Milky Way using their star as a lensing telescope, odds are that the “terrascope” proposed by Columbia University’s David Kipping, will be the largest in our home galaxy beyond the black-hole Event Horizon Telescope. The terrascope turns Earth into a kind of lens that could filter out light pollution and artificial satellites, and help find the signatures of life on exoplanets.
